Why do people in China like to keep silent when eating?

Because someone smacks their lips when eating, which affects their appetite!

For example, when we go out to a party together, everyone sits there and eats quietly, but if one person eats loudly, it will greatly affect our appetite, and we will all watch him not eat. Others are joking and silent when eating, which is the greatest respect for others.

In fact, China's ancestors did not leave this kind of etiquette, and it makes sense to exist. Many people don't know the concept of mouth. The so-called mouth mouth, that is, the sound of food and saliva mixed together, will certainly come out. Eating with your mouth closed will reduce the sound, while eating with your mouth open will make people eat more fragrant and the tongue will move more widely in your mouth. Although there is no sound when eating with your mouth closed, the range of tongue movement in your mouth will be more comfortable than eating with your mouth open.
